Register 23: GPIO ADC Control (GPIOADCCTL), offset 0x530
This register is used to configure a GPIO pin as a source for the ADC trigger.
Note that if the Port B GPIOADCCTL register is cleared, PB4 can still be used as an external trigger
for the ADC. This is a legacy mode which allows code written for previous devices to operate on
this microcontroller.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
